Question

The surface area of a sphere of radius 10 units is larger than the surface area of a cube with edge lengths of 10 units.

Answer 1

can someone explain this to me please?

Answer 2

Do you know what the equation for the surface area of a cube is?

Answer 3

And a sphere?

Answer 4

yes surface are of a sphere is (4/3){pie}radius(sq)

Answer 5

the surface are of a cube is 6(a)sq where a is length

Answer 6

Close. You're talking about the volume of a sphere. The surface area of a sphere is \(4 \pi r^2\). You have the cubic S.A. right though.

Answer 7

but the cube is still bigger than the sphere?
Surface A. of sphere; 4{pie} 10sq2= 400 { you don't calculate pie}
Surface A. of cube; 6(10)sq2 =600
i'm confused

Answer 8

Right. So the statement is false.
